RS485 control signal, lightning protector, 5v/12v/24V communication port, surge protector, lightning protection.
Brief introduction
The control signal lightning arrester is a lightning
protection measure developed by Zhejiang tohr Electric Co., Ltd.,
which is independently developed for signal circuit protection. The
surge protector is mainly used for industrial control system data
control signal, communication line, telemetry signal and remote
control signal. It is applied to the 1-2 and 2-3 areas of the
lightning protection area. Prevent direct lightning and overvoltage
damage to equipment.
Product specification
1. Working voltage:24V
2. Max continuous operating voltage(UC):30V
3. Voltage protective level(UP):<60V
4. Nominal discharge current(IN):10KA
5. Response time(NS): ≤10
6. Characteristic impedance: 75Ω
7. Insertion loss: ≤0.1dB
Working principle of product
The control signal surge protector is connected to the front
end of the protected equipment. When the transmission line is
impacted by the inductive thunder and other transient overvoltage,
the impact current is discharged to the earth through the
protection branch of the surge protector, and the output voltage is
placed in the allowable voltage range of the equipment, thus
ensuring the safety of the operating equipment.
Use of attention
1. identify the input / output interface identifier of
the lightning protector, input the external line and output the
connection device.
2. before the protector is connected to the system,
check the grounding resistance of the grounding grid first. It
should comply with the specification requirements.
3. grounding lines should be short, thick and straight,
so as to reduce the influence of distributed inductors on the
ability of lightning electromagnetic pulse.
Product features
1. using ultra low capacitance design, the signal
transmission characteristic is good.
2. it has self recovery function and provides multiple
protection under lightning prone environment.
3. advanced production process and beautiful appearance
